The Obama administration has oft made the argument that the Fourth Amendment -- which protects a citizen's "houses, papers, and effects, against unreasonable searches and seizures" -- is "inconvenient" for law enforcement and should be pruned back to a much more limited form. In its argument in favor of warrantless smartphone searches, the President's staff argues that notebooks, calendars, and pagers have all been found in past SCOTUS or Circuit Court rulings to be searchable without warrant (not eligible for Fourth Amendment protections).

He points out that the administration appears to have cherry-picked a case involving an older device (the case in question involved an classic "dumb" cell phone seized in a 2007 crack cocaine bust of a Mass. man). He says that asking the court to consider a case with outdated information may be an attempt to lead them to an inaccurate conclusion. He writes:

Given that the argument for treating cell phones differently from physical items hinges on the storage capacity and services available through smartphones, I think it would be very helpful for the Court to take a case involving a smartphone instead of a more primitive model. In recent years, smartphones quickly have become ubiquitous: About 35% of Americans owned one by May 2011, 46% owned one by February 2012, and 56% owned one by May 2013. (In case you’re wondering, 91% of Americans have cellphones, so about 61% of cell phones owned as of May 2013 are smart phones.) Reviewing a case with an earlier model phone would lead to a decision with facts that are atypical now and are getting more outdated every passing month.

He argues that it would be better for the SCOTUS to examine a separate case that law professor Stanford Univ.Jeff Fisherhas asked the SCOTUS to consider -- Riley v. California. That case involved a 2009 search of a customer's Samsung Electronics Comp., Ltd (KSC:005930) Instinct M800, an early smartphone. The case involved officers searching through a suspected gang member's smartphone for videos, pictures, and address book -- all without getting a warrant for the search, a key step of Fourth Amendment due process that prevents abuse.
